Guide to SharePoint Data Access in Blockbrain

Guide for Blockbrain users on choosing between SharePoint delegated access (Agent) and Knowledge Management Indexing (EPL Pipeline)

When integrating SharePoint with Blockbrain, users can choose between two main approaches:

• A. Knowledge Management Indexing (EPL Pipeline)

• B. SharePoint Delegated Access via Agent

This guide explains when to use each method, their pros and cons, and provides practical use-cases.

Criteria	Knowledge Management Indexing (EPL Pipeline)	SharePoint Delegated Access (Agent)
Data Volume	Small/Medium or Selective	Large
Cost	Higher (for large data)	Lower (selective access)
Answer Quality	High (Blockbrain controls search/indexing)	Limited (MS Graph API dependent)
Search/Analytics	Full	Limited
Use-Case	Comprehensive KM, Selective	Selective, cost-sensitive, agentic
Multi-Tool Workflows	No	Yes
Control of Search	Blockbrain	SharePoint (Microsoft Graph API)

Decision Criteria

A. Knowledge Management Indexing (EPL Pipeline)

When to Use:

• You need high-quality, comprehensive search and answers across your selected/specific SharePoint folders or files.

• Your SharePoint data volume is manageable (not extremely large).

• You want specific documents/folders indexed for advanced knowledge management features.

How it Works:

• The platform triggers an ETL pipeline to index selected SharePoint data (not the entire SharePoint).

• Data runs through Blockbrain’s knowledge extraction and indexing pipeline.

• Blockbrain controls the search and retrieval queries on its own index, enabling advanced and customizable search.

Pros:

• Best answer quality and search experience.

• Full content of indexed files is available.

• Enables advanced analytics and knowledge discovery.

• Selective indexing: You can choose only the folders/files you need.

Cons:

• High cost for large data volumes (gigabytes/terabytes).

• Indexing large SharePoint sites or many folders can cause cost spikes.

• Not suitable for massive datasets.

B. SharePoint Delegated Access via Agent

When to Use:

• Your SharePoint contains large volumes of data (many GBs or TBs).

• You want to limit costs by only connecting specific files or folders.

• You need on-demand access to selected SharePoint content.

• You want to combine SharePoint access with other agentic actions (e.g., drafting emails, cross-checking CRM, generating charts).

How it Works:

• The Agent connects to SharePoint with delegated access.

• You choose which files/folders to connect—no indexing or data extraction on our platform.

• Extraction, indexing, and search are controlled by SharePoint (Microsoft Graph API), not Blockbrain.

• Agentic tools can combine SharePoint actions with other workflows.

Pros:

• Cost-effective for large datasets.

• Flexible—connect only what you need.

• Avoids unnecessary indexing and storage costs.

• Can combine SharePoint access with other tools (e.g., email drafting, CRM checks, chart generation).

Cons:

• Answer quality and search capabilities are limited by the Microsoft Graph API (not by our platform). Note: We cannot influence the search quality provided by the API. For most use cases, this is sufficient.

• Not all content is available for AI-powered insights.

• Currently, it does not support SharePoint search folders.

Use-Cases

Use-Case 1: Small/Medium SharePoint Site

• Scenario: A team wants to search and analyze project documents (few GBs).

• Recommendation: Use Knowledge Management Indexing for best results.

Use-Case 2: Large Enterprise SharePoint

• Scenario: An organization has several TBs of archived data but only needs to access current project files.

• Recommendation:

  • Use Selective Indexing to index only the required folders via Knowledge Management, if advanced search is needed.

  • Alternatively, use SharePoint Delegated Access via Agent for on-demand, cost-effective access.

Use-Case 3: Cost-Sensitive Project

• Scenario: A department has a tight budget and only needs to access a handful of files for a short-term project.

• Recommendation: Use Delegated Access to avoid unnecessary indexing costs.

Use-Case 4: Cross-functional Tool Usage

• Scenario: A user needs to read a file from SharePoint, draft an email with its content, and cross-check information in a CRM.

• Recommendation: Use SharePoint Delegated Access via Agent to enable multi-tool workflows.

Recommendations

• For best answer quality and full knowledge management:

  • Use Knowledge Management Indexing (EPL Pipeline) for small to medium data volumes, or selectively index only the folders you need.

• For large datasets, cost control, or agentic workflows:

  • Use SharePoint Delegated Access via Agent to connect only what you need and combine with other tools.

Tip: Always assess your data volume, business needs, and workflow requirements before choosing the integration method.
